To all whom it may concern/.- 7

Be it known that I, CHARLES F. FoLsoM, a

citizen of the United States, residing at Stoneham, in the county ofMiddlesex and State of Massachusetts,haveinvented certain new and usefulImprovements in Wrenches; and I do hereby declare the following to be afull, clear,

; and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to wrenches; and it consists in the novelconstruction and combination of the parts hereinafter fully describedand claimed.

In the drawings, Figure l is a front view of the wrench. Fig. 2 is aside View of the wrench.

screw-thread.

E is a revoluble barrel provided with a screw-threaded portion 6 forengaging with the rack D. A circumferential groove f is formed in thebarrel, and g is a forked guide on the jaw C, which engages with thesaid groove. A bearing 71. is formed at the end of the barrel, and thishearing is pivoted in a socket i on the slidable jaw.

H represents springs secured to the slidable jaw and bearing against thebarrel E. These springs normally hold the barrel in engagement with therackand prevent the jaw C from sliding. I

The slidable jaw is moved for fine adj ustment by revolving the barrelwith the thumb and fingers. The slidable jaw is moved rapidly for largeradjustments by pressing the free end portion of the barrel away from theshank until its screw-thread is clear of the rack and then sliding thejaw O as far as desired upon the shank.

What I claim is In a Wrench, the combination, with a shank having astationary jaw and a toothed rack, of a slidable jaw provided with asocket and a forked guide, a revoluble finger-barrel provided with ahearing at one end pivoted in the said socket, and having acircumferential groove which engages with the said forked guide and ascrew'threaded portion arranged between the said bearing and groove, andmeans for normally holding the said screwthreaded portion in engagementwith the rack, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
